Abstract
A electrocrushing drill bit may include a bit body; an electrode coupled to a power source and the bit body, the electrode having a distal portion for engaging with a surface of a wellbore; a ground ring coupled to the bit body proximate to the electrode and having a distal portion for engaging with the surface of the wellbore, the electrode and the ground ring positioned in relation to each other such that an electric field produced by a voltage applied between the ground ring and the electrode is enhanced at a portion of the electrode proximate to the distal portion of the electrode and at a portion of the ground ring proximate to the distal portion of the ground ring; and an insulator coupled to the bit body between the electrode and the ground ring.
